TECHNICAL FIELD

The present invention relates to the field of communicationstechnologies, and in particular, to a method, a device, and a system forsynchronizing a physical layer state.

BACKGROUND

A DTX/DRX (discontinuous transmission/discontinuous reception) featureis introduced in the UMTS (universal mobile telecommunications system)R7 (release 7). This feature allows a terminal to discontinuouslytransmit/receive data at the uplink and downlink, thereby savingelectricity for the terminal and increasing the capacity at the networkside. When the terminal is connected to a network, an RNC (radio networkcontroller) admits access of the terminal, completes configuration witha NodeB (node base station) according to the DTX/DRX capability reportedby the terminal, and completes configuration with the terminal, so thatthe terminal may perform discontinuous transmission at the uplink ordiscontinuous reception at the downlink; the NodeB may performdiscontinuous transmission at the downlink or discontinuous reception atthe uplink. After the terminal is connected to the network, the RNC mayfurther initiate DTX/DRX re-configuration as required to maintain aDTX/DRX enabled or disabled state at the RRC (radio resource control)layer with the terminal; the NodeB may further activate or deactivate aDTX/DRX state at the physical layer for the terminal through an HS-SCCH(high speed shared control channel) order, thereby maintaining theDTX/DRX activated or deactivated state at the physical layer with theterminal.

An HS-SCCH less feature is further introduced in the UMTS R7. Forfirst-time transmission of HSDPA (high speed downlink packet access)data, no indication is made on the HS-SCCH channel, but the data isacquired through blind detection by the terminal for the HS-PDSCH (highspeed physical downlink shared control channel). If the detectionsucceeds, an acknowledgment response is sent to the NodeB, in which casethe NodeB sends a data block to the terminal; if the detection fails, noresponse is sent to the NodeB, in which case the NodeB will re-transmitthe previous data block, and make an indication on the HS-SCCH channel,thereby saving overhead of the HS-SCCH resources. The NodeB may alsoactivate or deactivate an HS-SCCH less state at the physical layer forthe terminal through the HS-SCCH order, thereby maintaining the HS-SCCHless activated or deactivated state at the physical layer with theterminal.

A DC-HSDPA (dual cell-HSDPA) feature is introduced in the UMTS R8, whichallows a terminal to receive HSDPA data at the same time in two cellswith different frequencies and same coverage and thereby obtain a highdownlink data transmission rate. A DC-HSUPA (dual cell-high speed uplinkpacket access) feature is further introduced in the UMTS R9, whichallows a terminal to send HSUPA data at the same time in two cells withdifferent frequencies and same coverage and thereby obtain a high uplinkdata transmission rate. The NodeB may also activate or deactivate aDC-HSDPA state or DC-HSUPA state at the physical layer for the terminalthrough the HS-SCCH order, thereby maintaining the DC-HSDPA or DC-HSUPAactivated or deactivated state at the physical layer with the terminal.

In the prior art, when the RNC re-configures the DTX/DRX feature,HS-SCCH less feature, DC-HSDPA feature, and DC-HSUPA feature, it willmaintain the enabled state of each of the features at the RRC layer withthe terminal; however, after re-configuration by the RNC, no definitesolution is provided for the state of each of the features at thephysical layer of the terminal. Therefore, different processing may beused at different terminals, thereby resulting in a problem where thephysical layer state of a feature at the terminal may be inconsistentwith that at the network side. For example, after the RNC re-configuresthe DTX/DRX feature, the DTX/DRX state at the physical layer of someterminals is an activated state by default, whereas some terminalsmaintain the previous DTX/DRX state at the physical layer by default. Ifthe default DTX/DRX state at the physical layer of a terminal happens tobe opposite to the DTX/DRX state at the physical layer maintained by theNodeB, data loss may occur during transmission, or even the terminal maysuffer call drops.

Third mode: if the terminal is a terminal that has a specified state atthe physical layer after the configuration at the RRC layercorresponding to the first feature is updated, the SRNC does not send afirst message to the base station, and notifies the base station toensure that the physical layer state of the first feature afterre-configuration is the same as the specified state; or, if the terminalis a terminal that has no specified state at the physical layer afterthe configuration at the RRC layer corresponding to the first feature isupdated, the SRNC sends a first message to the base station to notifythe base station to send, after the terminal updates the configurationat the RRC layer corresponding to the first feature, an HS-SCCH order tosynchronize with the physical layer state of the first feature of theterminal.

Fourth mode: if the terminal is a terminal that has a specified state atthe physical layer after the configuration at the RRC layercorresponding to the first feature is updated, the SRNC sends a firstmessage to the base station to notify the base station to ensure thatthe physical layer state of the first feature after re-configuration isthe same as the specified state; or, if the terminal is a terminal thathas no specified state at the physical layer after the configuration atthe RRC layer corresponding to the first feature is updated, the SRNCsends a first message to the base station to notify the base station tosend, after the terminal updates the configuration at the RRC layercorresponding to the first feature, an HS-SCCH order to synchronize withthe physical layer state of the first feature of the terminal.

In another embodiment of the present invention, the according to thenotification, controlling the physical layer state of the first featureafter the re-configuration in 202 may include: if the notificationindicates that the terminal has a specified state at the physical layerafter the configuration at the RRC layer corresponding to the firstfeature is updated, ensuring, by the base station, that the physicallayer state of the first feature after the re-configuration is the sameas the specified state; or, if the notification indicates that theterminal has no specified state at the physical layer after theconfiguration at the RRC layer corresponding to the first feature isupdated, after the terminal updates the configuration at the RRC layercorresponding to the first feature, sending, by the base station, a highspeed shared control channel (HS-SCCH) order to synchronize with thephysical layer state of the first feature of the terminal.

In another embodiment of the present invention, the according to thenotification, controlling the physical layer state of the first featureafter the re-configuration in 202 may include:

if the base station receives a first message sent from the SRNC,ensuring, by the base station, that the physical layer state of thefirst feature after the re-configuration is the same as the specifiedstate; or, if the base station does not receive a first message sentfrom the SRNC, after the terminal updates the configuration at the RRClayer corresponding to the first feature, sending, by the base station,an HS-SCCH order to synchronize with the physical layer state of thefirst feature of the terminal; or, if the base station does not receivea first message sent from the SRNC, ensuring, by the base station, thatthe physical layer state of the first feature after the re-configurationis the same as the specified state; or, if the base station receives afirst message sent from the SRNC, after the terminal updates theconfiguration at the RRC layer corresponding to the first feature,sending, by the base station, an HS-SCCH order to synchronize with thephysical layer state of the first feature of the terminal; or, if thebase station receives a first message sent from the SRNC, and the firstmessage indicates that the terminal has a specified state at thephysical layer after the configuration at the RRC layer corresponding tothe first feature is updated, ensuring, by the base station, that thephysical layer state of the first feature after the re-configuration isthe same as the specified state; or, if the base station receives afirst message sent from the SRNC, and the first message indicates thatthe terminal has no specified state at the physical layer after theconfiguration at the RRC layer corresponding to the first feature isupdated, after the terminal updates the configuration at the RRC layercorresponding to the first feature, sending, by the base station, anHS-SCCH order to synchronize with the physical layer state of the firstfeature of the terminal.

According to the method provided in this embodiment, by receiving anotification from an SRNC, a base station controls, according to thenotification, a physical layer state of a first feature afterre-configuration, so that after the terminal updates the configurationat the RRC layer corresponding to the first feature, the network sidecan synchronize with the physical layer state of the terminal, whichsolves the problem where the physical layer state of a feature at theterminal may be inconsistent with that at the network side, therebyavoiding loss during data transmission and preventing call drops of theterminal.

Referring to FIG. 3, this embodiment provides a method for synchronizinga physical layer state, which is illustrated by taking the DTX/DRXfeature as an example, and may be described as follows:

301: A terminal is connected to a network, and sends an uplink RRCsignaling to an SRNC.

Here, capability information for the DTX/DRX feature and access layerversion information of the terminal are carried in the uplink RRCsignaling.

302: After receiving the RRC signaling sent from the terminal, the SRNCacquires the capability information for the DTX/DRX feature of theterminal and the access layer version information of the terminal fromthe RRC signaling.

303: The SRNC judges, according to the capability information for theDTX/DRX feature of the terminal and the access layer version informationof the terminal, a version of the terminal and whether the terminal hasa capability of supporting a first feature.

For example, if the version of the terminal is R9 or a version laterthan R9 and the terminal has the capability of supporting the firstfeature, 304 is executed; if the version of the terminal is R8 or aversion earlier than R8 and the terminal has the capability ofsupporting the first feature, 306 is executed.

304: The SRNC determines that the terminal is a terminal that has aspecified state at a physical layer after configuration at an RRC layercorresponding to the DTX/DRX feature is updated, and accordingly sends afirst message through an Iub interface to a NodeB to notify the NodeB toensure that the physical layer state of the DTX/DRX feature afterre-configuration is the same as the specified state.

305: The NodeB receives the first message, and, after the terminalupdates the configuration at the RRC layer corresponding to the DTX/DRXfeature, configures the physical layer state of the DTX/DRX feature asthe specified state, which may avoid sending an HS-SCCH order, therebysaving overhead of the HS-SCCH signaling.

Here, the specified state may be clearly regulated in the protocol, forexample, if the protocol regulates that “the physical layer state afterthe configuration at the RRC layer corresponding to the DTX/DRX featureis an activated state”, the NodeB configures, after the terminal updatesthe configuration at the RRC layer corresponding to the DTX/DRX feature,the physical layer state of the DTX/DRX feature as the activated state.

306: The SRNC determines that the terminal is a terminal that has nospecified state at the physical layer after the configuration at the RRClayer corresponding to the DTX/DRX feature is updated, and accordinglydoes not send a first message to the NodeB.

307: If the NodeB does not receive the first message, after the terminalupdates the configuration at the RRC layer corresponding to the DTX/DRXfeature, the NodeB sends an HS-SCCH order to synchronize with thephysical layer state of the DTX/DRX feature of the terminal.

Referring to FIG. 4, this embodiment provides a method for synchronizinga physical layer state, which is illustrated by taking the HS-SCCH lessfeature as an example, and may be described as follows:

401: A terminal is connected to a network, and sends an uplink RRCsignaling to an SRNC.

Here, capability information for the HS-SCCH less feature and accesslayer version information of the terminal are carried in the uplink RRCsignaling.

402: After receiving the RRC signaling sent from the terminal, the SRNCacquires the capability information for the HS-SCCH less feature of theterminal and the access layer version information of the terminal fromthe RRC signaling.

403: The SRNC judges, according to the capability information for theHS-SCCH less feature of the terminal and the access layer versioninformation of the terminal, a version of the terminal and whether theterminal has a capability of supporting a first feature; if the versionof the terminal is R9 or a version later than R9 and the terminal hasthe capability of supporting the first feature, 404 is executed; if theversion of the terminal is R8 or a version earlier than R8 and theterminal has the capability of supporting the first feature, 406 isexecuted.

404: The SRNC determines that the terminal is a terminal that has aspecified state at a physical layer after configuration at an RRC layercorresponding to the HS-SCCH less feature is updated, and accordinglydoes not send a first message to a NodeB, and notifies the NodeB toensure that the physical layer state of the HS-SCCH less feature afterre-configuration is the same as the specified state.

405: If the NodeB does not receive the first message, after the terminalupdates the configuration at the RRC layer corresponding to the HS-SCCHless feature, the NodeB configures the physical layer state of theHS-SCCH less feature as the specified state, which may avoid sending anHS-SCCH order, thereby saving overhead of the HS-SCCH signaling.

Here, the specified state may be clearly regulated in the protocol, forexample, if the protocol regulates that “the physical layer state afterthe configuration at the RRC layer corresponding to the HS-SCCH lessfeature is a deactivated state”, the NodeB configures, after theterminal updates the configuration at the RRC layer corresponding to theHS-SCCH less feature, the physical layer state of the HS-SCCH lessfeature as the deactivated state.

406: The SRNC determines that the terminal is a terminal that has nospecified state at the physical layer after the configuration at the RRClayer corresponding to the HS-SCCH less feature is updated, andaccordingly sends a first message to the NodeB.

407: The NodeB receives the first message, and after the terminalupdates the configuration at the RRC layer corresponding to the HS-SCCHless feature, sends an HS-SCCH order to synchronize with the physicallayer state of the HS-SCCH less feature of the terminal.

Referring to FIG. 5, this embodiment provides a method for synchronizinga physical layer state, which is illustrated by taking the DC-HSDPAfeature as an example, and may be described as follows:

501: A terminal is connected to a network, and sends an uplink RRCsignaling to an SRNC.

Here, capability information for the DC-HSDPA feature and access layerversion information of the terminal are carried in the uplink RRCsignaling.

502: After receiving the RRC signaling sent from the terminal, the SRNCacquires the capability information for the DC-HSDPA feature of theterminal and the access layer version information of the terminal fromthe RRC signaling.

503: The SRNC judges, according to the capability information for theDC-HSDPA feature of the terminal and the access layer versioninformation of the terminal, a version of the terminal and whether theterminal has a capability of supporting a first feature; if the versionof the terminal is R9 or a version later than R9 and the terminal hasthe capability of supporting the first feature, 504 is executed; if theversion of the terminal is R8 or a version earlier than R8 and theterminal has the capability of supporting the first feature, 506 isexecuted.

504: The SRNC determines that the terminal is a terminal that has aspecified state at a physical layer after configuration at an RRC layercorresponding to the DC-HSDPA feature is updated, and accordingly sendsa first message through an Iub interface to a NodeB, where the firstmessage is used to instruct the NodeB to ensure that the physical layerstate of the DC-HSDPA feature after re-configuration is the same as thespecified state.

505: The NodeB receives the first message, and, after the terminalupdates the configuration at the RRC layer corresponding to the DC-HSDPAfeature, configures the physical layer state of the DC-HSDPA feature asthe specified state without sending an HS-SCCH order, thereby savingoverhead of the HS-SCCH signaling.

Here, the specified state may be clearly regulated in the protocol, forexample, if the protocol regulates that “the physical layer state afterthe configuration at the RRC layer corresponding to the DC-HSDPA featureis an activated state”, the NodeB configures, after the terminal updatesthe configuration at the RRC layer corresponding to the DC-HSDPAfeature, the physical layer state of the DC-HSDPA feature as theactivated state.

506: The SRNC determines that the terminal is a terminal that has nospecified state at the physical layer after the configuration at the RRClayer corresponding to the DC-HSDPA feature is updated, and accordinglysends a second message through the Iub interface to the NodeB, where thesecond message is used to instruct the NodeB to send, after the terminalupdates the configuration at the RRC layer corresponding to the DC-HSDPAfeature, an HS-SCCH order to synchronize with the physical layer stateof the DC-HSDPA feature of the terminal.

507: The NodeB receives the second message, and after the terminalupdates the configuration at the RRC layer corresponding to the DC-HSDPAfeature, sends an HS-SCCH order to synchronize with the physical layerstate of the DC-HSDPA feature of the terminal.

Referring to FIG. 6, this embodiment provides a method for synchronizinga physical layer state, which is illustrated by taking the DC-HSUPAfeature as an example, and may be described as follows:

601: A terminal is connected to a network, and sends an uplink RRCsignaling to an SRNC.

Here, capability information for the DC-HSUPA feature is carried in theuplink RRC signaling.

602: After receiving the RRC signaling sent from the terminal, the SRNCacquires the capability information for the DC-HSUPA feature of theterminal from the RRC signaling.

603: The SRNC judges whether the RRC signaling includes indicationinformation about the physical layer state of the terminal; if yes, 604is executed; otherwise, 609 is executed.

604: The SRNC determines that the terminal is a terminal that has aspecified state at a physical layer after configuration at an RRC layercorresponding to the DC-HSUPA feature is updated, and accordinglyfurther judges, according to the indication information about thephysical layer state, whether the physical layer state of the terminalafter the configuration at the RRC layer corresponding to the DC-HSUPAfeature is updated is an activated state or a deactivated state; if itis the activated state, 605 is executed; if it is the deactivated state,607 is executed.

Here, the indication information about the physical layer state may beexpressed by using multiple forms, for example, true may be used toindicate that the physical layer state of the terminal after theconfiguration at the RRC layer is updated is the activated state; falseis used to indicate that the physical layer state of the terminal afterthe configuration at the RRC layer is updated is the deactivated state,which is not particularly limited in the embodiment of the presentinvention.

605: Send a first message through an Iub interface to a NodeB, where thefirst message is used to indicate that the physical layer state afterthe terminal updates the configuration at the RRC layer corresponding tothe DC-HSUPA feature is the activated state.

606: The NodeB receives the first message, and after the terminalupdates the configuration at the RRC layer corresponding to the DC-HSUPAfeature, configures the physical layer state of the DC-HSUPA feature asthe activated state.

607: Send a second message through the Iub interface to the NodeB, wherethe second message is used to indicate that the physical layer stateafter the terminal updates the configuration at the RRC layercorresponding to the DC-HSUPA feature is the deactivated state.

608: The NodeB receives the second message, and after the terminalupdates the configuration at the RRC layer corresponding to the DC-HSUPAfeature, configures the physical layer state of the DC-HSUPA feature asthe deactivated state.

609: The SRNC determines that the terminal is a terminal that has nospecified state at the physical layer after the configuration at the RRClayer corresponding to the DC-HSUPA feature is updated, and accordinglydoes not send a message to the NodeB.

610: If the NodeB does not receive a message from the SRNC, after theterminal updates the configuration at the RRC layer corresponding to theDC-HSUPA feature, the NodeB sends an HS-SCCH order to synchronize withthe physical layer state of the DC-HSUPA feature of the terminal.

Definitely, 609 and 610 may also be replaced as follows: The SRNCdetermines that the terminal is a terminal that has no specified stateat the physical layer after the configuration at the RRC layercorresponding to the DC-HSUPA feature is updated, and accordingly sendsa third message through the Iub interface to the NodeB, where the thirdmessage is used to instruct the NodeB to send, after the terminalupdates the configuration at the RRC layer corresponding to the DC-HSUPAfeature, an HS-SCCH order to synchronize with the physical layer stateof the DC-HSUPA feature of the terminal; the NodeB receives the thirdmessage, and after the terminal updates the configuration at the RRClayer corresponding to the DC-HSUPA feature, sends an HS-SCCH order tosynchronize with the physical layer state of the DC-HSUPA feature of theterminal.

In this embodiment, the SRNC may further control the NodeB whether tosend the HS-SCCH order to ensure synchronization with the physical layerstate of the terminal, thereby avoiding inconsistency between thephysical layer states of the first feature at the terminal and thenetwork side. The specific description may be as follows:

If the SRNC judges that the terminal is a terminal that has a specifiedstate at the physical layer after the configuration at the RRC layercorresponding to the first feature is updated, the NodeB is notified tosend an HS-SCCH order to control the physical layer state of the firstfeature; or, if the SRNC judges that the terminal is a terminal that hasno specified state at the physical layer after the configuration at theRRC layer corresponding to the first feature is updated, the NodeB isnotified not to send an HS-SCCH order to control the physical layerstate of the first feature.

Any one message sent by the SRNC to the base station involved in thisembodiment may be sent through the Iub interface to the base station; orsent through the Iur interface to the DRNC, and then forwarded by theDRNC to the base station. Here, the any one message may be a signalingor FP data frame.

In this embodiment, when being connected to the network, the terminalmay further report one or more of the DTX/DRX feature, HS-SCCH lessfeature, DC-HSDPA feature, and DC-HSUPA feature, which is notparticularly limited in the embodiment of the present invention.

According to the method provided in this embodiment, it is judged,according to relevant information about a first feature reported by aterminal, whether the terminal is a terminal that has a specified stateat a physical layer after configuration at an RRC layer corresponding tothe first feature is updated, and a NodeB is notified accordingly tocontrol, according to whether the terminal has the specified state atthe physical layer after the configuration at the RRC layercorresponding to the first feature is updated, a physical layer state ofthe first feature after re-configuration, so that after the terminalupdates the configuration at the RRC layer corresponding to the firstfeature, the network side can synchronize with the physical layer stateof the first feature of the terminal, which solves the problem where thephysical layer state of a feature at the terminal may be different fromthat at the network side, thereby avoiding loss during data transmissionand preventing call drops of the terminal.

Here, during notification of the base station, notification may beperformed by using the mode of sending a message, or may also beperformed by using the mode of not sending a message, thereby achievinghigh flexibility.

Further, for a terminal that has a specified state at the physical layerafter the configuration at the RRC layer corresponding to the firstfeature is updated, the NodeB does not need to send an HS-SCCH order tosynchronize with the physical layer state of the feature of theterminal, which greatly saves overhead of the HS-SCCH signaling, therebysaving precious wireless network resources.
